Preheat your oven to 350°F (175°C).

Cream together the butter and sugars in a large bowl until light and fluffy, about 3-5 minutes.

Add the eggs one at a time, mixing well after each addition.

Mix in the vanilla extract.

Combine the dry ingredients—flour, baking soda, and salt—in a separate bowl before gradually adding them to the wet ingredients. Stir until just combined.

Fold in the chopped pistachios and white chocolate chips gently.

Scoop tablespoon-sized balls of dough onto a lined baking sheet, leaving space between each one.

Bake for 10-12 minutes or until the edges are lightly golden and the centers are set but still soft. Let them cool on the sheet for a few minutes before transferring to a wire rack.
